These soft rubber trays also are more liable to destruction and have not got the physical strength of the hard rubber product. Also their weight for a given size is relatively great; and since the edges of the trays are flexible, there is also considerable danger of spillage of the contents by distortion of the edges when weight is accidentally placed thereupon.

A tray made in accordance with my invention has all the advantages and none of the disadvantages of the prior commercial product. It is strong, durable, stable and practically fool-proof; It may be readily maintained in sanitary condition and in all respects meets the requirements of purpose for which intended.
